POROUS CRYSTALLINE MATERIAL (ZEOLITE ITQ-21), THE PREPARATION METHOD THEREOF AND THE USE OF SAME IN THE CATALYTIC CONVERSION OF ORGANIC COMPOUNDS

摘要

The invention relates to a porous crystalline material (ITQ-21) which, in it s calcinated form, has chemical composition (1) wherein (n + m) is at least 5; X is a trivalent element; Z is Ge; y is at least one tetravalent element different from Ge; and the Y/Z ratio is at least 1. The X-ray diffraction values of said porous crystalline material are given in Table 1. The inventi on also relates to a method of preparing the material in the presence of fluori de ions and using N(16)- methylsparteine as a structure directing agent. The inventive material can be used in its acid form and in the form of a bifunctional catalyst in aromatic alkylation, hydrocracking and catalytic cracking processes.
